Design Explorer
New Features
- Design Explorer Release Highlights
- Watch this video to learn more about Design Explorer features in 2023.
- Response Creation from HW Session File
- This feature builds upon the generic response creation added in the HyperWorks 2022.3 release. With this enhancement, you can define responses and goals within a HyperWorks session, and then add and use them in their explorations in Design Explorer. Define and use any response that can be evaluated within the TableView client of the HyperWorks session based on plots, animations, and any corresponding calculations.
- Automatic Design Variable Link Creation
- Using shape matching AI, you can automatically link symmetric matching parts from their exploration design variables, saving the time and effort spent previously, and eliminating potential human error. A preview feature allows for a visual preview of matching parts before links are created.
- Curve Prediction
- Viewing real time predictions of response curves is now available. Moving the design variable value sliders will update the predicted curve according to the current slider values. With the new curve predictions being added alongside existing scalar and field predictions already available, Design Explorer now supports a complete set of predictive tools.
- ExpertAI
- ExpertAI uses the clustering tools added to the Design Explorer in HyperWorks 2022.3 and allows leveraging clusters as a constraint in an optimization. The ExpertAI workflow provides the opportunity to ensure that their designs are not only optimal but that they also conform to desired criteria such as a particular deformation mode which could not otherwise be guaranteed through optimization alone.
Extensions
Highlights
- Extensions Release Highlights
- Watch this video to learn more about Extension features in 2023.
- Autoloading of extensions of newly added Extensions
Enhancements
- Autoload Extensions
- Extensions can be autoloaded using the “extends” entry when the
application starts or is loaded with the environment variable
HWX_PLUGINS
.
Known Issues
- To show the Extension loaded in different profiles even when no GUI access
points like ribbons, toolbars or menus are available requires that each
profile is loaded with at least one entry. The example below shows the empty HyperMesh and HyperView profiles with the (dummy) entry resources. This entry will not be required in future versions to show the extension loaded in these profiles.
Resolved Issues
- The “displayName” is no longer the same as the “name”
Fields
Enhancements
- Updated Convection Mapping
- Convection mapping now leverages the new OptiStruct CONVG load entity, which also results in much faster realizations for large models.
- Faster Force Mapping
- Improved force balance method for better reliability and faster realization times with large models.
Resolved Issues
- Corrected bug that was causing scale factors to be applied twice with repeated realizations.
- Corrected issue with tolerance not updating.
- Corrected application error when clicking on some parts of the realization dialog.
General
New Features
- HyperMesh Release Highlights
- Watch these videos to learn more about new HyperMesh features in 2023.
- Keyboard Shortcuts Editor
- HyperMesh shortcuts are now configurable using the new Keyboard Shortcuts Editor. Access it from the View menu to review and edit existing shortcuts, or create new ones. Shortcuts can be assigned to a list of registered application tools and functions, as well as custom Python or Tcl scripts.
- Position Tool
- A new Position mode is added to the Move tool. In this mode, you can position the selected entities by picking one, two, or three source and target location pairs. The source locations represent starting reference points, which are matched with their corresponding targets to produce a transformation.
- Calculate Workflow
- New COG and MOI calculation options have been added to:
- Calculate values in a local coordinate system.
- Calculate MOI around coordinate system center or COG.
- Consider lumped mass in COG and MOI calculations (valid for Radioss and LS-DYNA profiles only).
- Quick Advanced Selection Menu (Alt+Select)
- It is now possible to switch the active Quick Advanced Selection method (Alt+Select) for any current selection via this new quick menu, accessible via the comma ( , ) key. The shortcut for this function is also configurable in the new Keyboard Shortcut Editor.
- Ribbon Hints
- Ribbon hints have been added to help identify tools that have multiple pick targets or open a secondary ribbon. They are small indicators that appear in the ribbon between a tool’s icon and label. The number of dots represents the number of pick targets in a tool, including some that are hidden until hovering over the tool.
Enhancements
- Improvements to invoke speed.
- General performance improvements in user interaction with graphics/GUI (menus, guide bars, dialogs, model manipulation, and so on).
- Default shortcuts for the following selection actions have been reassigned:
- Advanced Selection (configurable): period ( . )
- Quick Advanced Selection menu (configurable): comma ( , )
- Selection Search (Entity Editor only, not configurable): forward slash ( / )
- Selection is now restored on undo for ordered and topology-based selectors.
- Hovering over curved lines shows the line length along with the radius.
- New shortcuts added for the Save selection and Retrieve selection actions: Ctrl+W and Ctrl+Shift+W.
- Drag and drop action is now supported for session files & Python scripts. Auto color now uses a random color palette that makes use of our expanded RGB colors.
- Newly created collectors or imported files with no color data are assigned colors from our accessibility color palette that are more visible in light/dark theme and by individuals with some types of color blindness.
- The context menu is now accessible in more selectors, regardless of their UI modality state.
- Current Collector selectors in the status bar area have new options to toggle entity icons, color, and show/hide IDs; they also make better use of available space for names and IDs. The new options are available in .
Known Issues
- File Open/File Save Dialogs and
Message Boxes:
- There are inconsistencies seen in the appearance of the following
types of dialogs:
- File Open
- File Save
- Message Boxes
- Based on the available file extension filters in File Open and File Save dialogs, and how those dialogs or a message box are brought up, the appearance/style of the dialog can differ from other instances of those dialogs.
- Some of these dialogs can go behind the main application when clicking elsewhere in the application, requiring you to bring them back to the foreground or reposition the application.
- Example showing the different versions of the File
Open dialog:
- There are inconsistencies seen in the appearance of the following
types of dialogs:
- When running in a NICE/DCV environment, there are drawing issues with the HyperWorks Toolbelt and Advanced Capture.
- Any legacy or custom Tk dialogs which may have been coded to operate using hard-coded keyboard shortcuts continue to expect the originally designated shortcut key, even if an equivalent HyperMesh shortcut has been edited using the Keyboard Shortcut Editor.
- HyperWorks may hang on re-launch if the license is close to expiring and the
license expiration warning dialog appears after a non-default browser was
active on previous shutdown.
- To avoid this, one of the following environment variables can be
used:
- ALM_NO_EXPIRE_WARNING: Disables the expiration warning.
- ALM_EXPIRE_DAY_WARNING: Specifies the number of days before license expiration warning message is given (default is 30).
- If one of the environment variables listed above is not used to avoid the issue, and the issue is seen, deleting the settings files resolves the issue.
- To avoid this, one of the following environment variables can be
used:
- For Windows 11: On a multi-window page with two or more HyperMesh windows
and at least one HyperView window, sometimes loading a model via the
File Open dialog launched from HyperView's Load
Model panel does not properly update the panel with the file name. This
prevents you from loading the file.
- If this issue is seen, you can load the file by copying and pasting, or directly typing the file path/name into the Open Model panel and clicking Apply.
- The HyperMesh session can freeze if you open the File menu while the Import Options dialog is launching (but before it is displayed). If this happens, switch to another application and then return to HyperMesh to resolve the issue.
- Launch times for HyperMesh have improved compared to those seen in 2022.3 for the new interface. However, there is still ongoing activity to further improve, particularly on first invoke, for certain network configurations.
- In multi-window layouts, longer guide bars may be truncated. To resolve the issue, resize the modeling window to be wider or expand the window so the guide bar is able to expand completely.
- Launch times for HyperMesh have improved over those seen in 2022.3 for the New HyperMesh. However, there is still ongoing activity to make additional improvements, particularly on first invoke, for certain network configurations.
- In multi-window layouts, longer guide bars may be truncated. To resolve this issue, resize the graphics area to be wider, or expand the window so that the guide bar is able to draw completely when it's accessed.
- If the advanced color selector is opened from the modeling window context menu, typing in the edit fields (red, green, blue, hex) is not possible; the arrow buttons can still be used to increment/decrement the red/green/blue values. To avoid this issue, open the color selector by clicking on the color in the browser or Entity Editor instead of from the modeling window context menu.
- In certain use cases, the outputs pushed to the Tcl Command Window during script execution are delayed until the script has finished. As a temporary solution, replace the stdout channel with a user-defined opened channel, then push the information to a text file.
- In certain cases, when launching directly into a post client (HyperView, HyperGraph, and so on) using the -clientconfig command line option, the client-specific browser cannot be opened. To avoid this, use the provided client-specific launch scripts (hv, hg, and so on) instead of the -clientconfig command line option.
- The LMB+RMB mouse customization does not work and will be disabled this release.
- After switching from HyperMesh to one of the post clients (HyperView, HyperGraph, and so on), certain function keys not used as shortcuts in the clients can open the HyperMesh secondary ribbon with blank icons or exit the idle context. To resolve this issue, switch to a context available within the client and then exit the context.
- On Windows, a segmentation error on shutdown can occur if HyperGraph, HyperView, or MotionView is opened from the Start menu, MediaView is opened from the Startup dialog, and the client is changed to HyperMesh before shutting down. To avoid this error, select HyperMesh from the Start menu instead of HyperGraph, HyperView, or MotionView, and open MediaView from the Startup dialog.
- After exiting HyperMesh on Linux, error messages can be seen in the terminal window if the session has been left idle for some time.
Resolved Issues
- Batch mode (-b) is now working for the new interface.
- Capturing images in dark theme when publishing now maintains the dark background instead of switching to a white background.
- Drag-and-drop of .hm and .mvw files into the modeling window on Linux is now working.
- There is no longer an error when importing/opening files from a directory with non-ASCII characters in the path on Linux.
- Many cases of dialogs/context menus coming up on the incorrect monitor in a multi-monitor setup have been resolved.
- When entering the Show/Hide tool, previous selections are not automatically carried into the tool anymore (this was causing them to be hidden immediately after entering the tool).
- Fixed an issue with some Rigid Body entities not being available for selection in the modeling window when outside of a tool.
- Fixed some inconsistent entity names between browser and modeling windows.
- Performance issue while populating Organize Reference dialog when moving components between includes.
- Tag color changes when you move the associated node.

- A new automatic creation mode pairs a part’s PDM mesh flag with the control's mesh flag to automate the creation process. This ensures the right type of representations are created for the right parts.
- PDM Live Support for Windchill
- PDM live now supports Windchill integration. Now you can directly download/upload data from the HyperMesh Part Browser to Windchill.
- AMDC HyperMesh Integration
- You can log in and download materials from AMDC. This integration is available out-of-box, but you need AMDC log in credentials.
- Subsystem Instancing
- Subsystem instancing has been introduced allowing the duplication and repositioning of subsystems. Avoid making repetitive changes to multiple, identical subsystems by making the change once and using instancing and subsystem representations to load the same change in all instanced locations.
- Specify number of CPUs used by BatchMesher
-
- A new option was added to the preferences that you can use to define the number of CPUs allocated for BatchMesher operations.
- The default is to let HyperMesh automatically choose, as before, but now you can manually select a specific number of CPUs to use.
Enhancements
- Library Manager
- The Library Manager’s updated layout allows for better organization and overview of all libraries. It serves as a centralized hub for registering and connecting all three types of libraries (Part, Subsystem, and Material). For direct access to the Library Manager, select the Libraries tool from the Assembly ribbon.
- Attribute Tables
- All available metadata associated with parts can now be listed in the Part Browser by adding new columns. To add a new column, from the entity editor right-click on specific metadata, and then select Add Column.
- Renumber
-
- The ordered selection for renumber was updated to use a specific entity selector. You can now select ordered renumbering by selecting a List option.
- The method to display IDs inside Renumber is now consistent with the method outside of the tool. Use with a selection made to show the IDs. The display of IDs is now passed correctly into and out of Renumber and Spatial Renumber contexts from idle.
- Any unresolved IDs are now shown in the text box inside the Renumber tool so you can see when these entities are not renumbered.
- Auto save Part representations
- When importing a monolithic geometry file, a single file that contains multiple parts, you no longer need to save representations for these parts before the creation process works. BatchMesher requires a representation file per part for input in the create work flow. When using a monolithic file, the representation is automatically saved when the representation name is assigned to the part, in session, when you try and create representations.
